KABUL (AFP) - A Taliban suicide bomber targeted a provincial governor in northern Afghanistan on Tuesday, killing two civilians and wounding another two, the interior ministry said. The attack struck the usually peaceful province of Parwan, when the bomber tried to enter the compound of governor Basir Salangi. At around 10:45am (0615 GMT) Tuesday, a suicide bomber detonated himself in front of the gate of the Parwan governors compound. As a result, two civilians including a woman were martyred and two others injured, the ministry said. Interior ministry spokesman Sediq Sediqi said it was not immediately clear why the attacker hit the entrance but that he may have been targeting a car coming out of the compound which he mistakenly thought was the governors. Elsewhere in Afghanistan, three policemen were killed by a landmine blast while out on patrol Monday in the southern province of Uruzgan, said Amanullah Hotaki, the chief of the local provincial council. Also Monday, two men - one a shopkeeper and the other a foreign forces contractor - were shot dead in the southern city of Kandahar, police said. Taliban spokesman Qari Yosuf Ahmadi took responsibility for all the attacks.
